I bought the last Pega-Stol wingkit for the Z-701 from Dedalius' founder, Gilles Boulanger, Phone: 1-819 563-4121 about six years ago.. He sold the mfr'ng rights to someone in Alaska shorly thereafter and I haven't heard anymore about the wingkit since. Gilles is in his mid-eighties now and wanted to get out of the mfr'ng business and spend more time flying. The principals who founded the company were an aircraft designer, an aerodynamicist and a professor of engineering.
The quality of the design and fabrication of the components seem better than the Zenith parts that came with my 701 kit which were certainly very good. The Dedalius parts are waterjet cut including all rivet holes,insuring distortion-free shapes with no effect on heat treatment, as compared to laser cutting or shearing. The fuel tanks are roto-molded one piece polyethelene with smoothly radiused edges as opposed to a welded unit made from several pieces with heat affected seams at the areas of highest stress and corners that can trap moisture and corrode. The slats move on rollers and open /close smoothly with aerodynamic pressure. The wing is a thinner NACA airfoil than the stock Zenith wing and is more than 10% faster at cruise. The movable slats also allow a 10% slower landing speed with good control. Gilles says he routinely lands at 25 mph!
I'm still constructing my 701 after several interruptions for family illnesses, a cross-country move and now joint problems of my own that preclude standing for long periods. As a 70 year old retired aerospace engr.(Hughes Aircraft), I probably would have bought a finished plane had I known what the future held, but hindsight ...
I might consider selling the entire kit including the wings, in case you're interested. I have all the doumentation, aero analyses, and DVDs of the construction process including the aircraft flying.
Hope this helps,
